ABRAM B. HERB, OF LANCASTER, PENNSYLVANIA, ASSIGNOR OF ONE-THIRD T0 ELAM M. ROYER AND ONE-THIRD TO JOHN H. MOSElVIAN, BOTH OF LANCASTER, PENNSYL- VANIA.

CAN-HOLDING DEVICE FOR GAN-WASHING MACHINES.

Specification of Letters Patent.

Application filed July 31, 1914. Serial No. 854,261.

To all whom it may concern:

Be it known that I, ABRAM B. HERB, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Can- Holding Devices for Can-Washing Machines, of which the following is a. specification, reference being had therein to the accompanying drawing.

This invention relates to can holding devices for can washing machines, and the object is to provide for the purpose indicated certain novel construction which may include a pair of relatively movable can inclosing members, means including a plurality of shafts for mounting and operating said members, and a tubular shaft carrying brush mounting devices and adapted to inclose a duct through which water and steam may. be supplied to the brushes.

With the foregoing and other objects in view, the invention consists in the construction, combination, and arrangement of elements hereinafter described and claimed.

In the accompanying drawings,

Figure 1 is a perspective view, showing the can holding means in a lowered and operative position.

F ig. 2 is also a perspective view, the can holding means being raised and open, and a guard member or casing therefor being removed.

Fig. 3 is a detail view of mechanism.

Fig. 1 is a perspective view, showing the construction at the rear of the machine.

Fig. 5 is a perspective view, from another angle.

Fig. 6 is a detail view, showing the means for mounting the brushes.

Fig. 7 shows the brush shaft in vertical section. 7

Figs. 8, 9 and 10 are detail views showing; means for operating the can inclosing members.

In the construction of the machine I provide a frame 1, to which is secured a le part of the lever or brace frame 2, formed with vertica bearings 3 and 1, within which is rotatably mounted the hollow brush supporting shaft 5 (Fig. 2). A steam and water duct shown in Fig. 7 and described below, extends through this shaft 5. p

The main frame 1 is provided with bearings 6 and 7 Within which is slidably mounteda' hollow shaft 8 (Fig. 2), upon which the can holding mechanism is mounted, and there is also secured to frame 1, on the back thereof, a vertical guide rod 9. Clamps 10 are used in effecting this connection. 4

The can holding mechanism comprises a casting 11 mounted on hollow shaft 8, the casting supporting arms 12 which are pivoted thereon, these arms having substantially a hinge connection. Thearms support and control the two halves of the can holding frame 13, the said halves being normally retained in a closed position by springs 14:, mounted on rods 15 extending transversely through arms 12.

The casting 11 is provided with bearings 16 in which is rotatably mounted a stud shaft 17 carrying a sprocket wheel 18 engaged bya chain 19 passlng over sprocket wheel 20 secured on shaft 21, mounted within hollow shaft 8. Secured to the shaft 17 is a member 22 having opposite arms 23 pivoted to links 24 which are pivotally connected to the arms 12. This construction permits of the swinging of arms 12 against the tension of springs 14:, and thus opening the can holding means. Below the casting 11 is a tation in the frame while the brushes mentioned below are cleaning the interior, and is then released and rotates with the brushes on the brush shaft, the brushes 153 then acting on the exterior.

The main brush mechanism comprises a hollow shaft 5, on which are mounted col lars 28 and 29, shown in Fig. 6. Collar 28 is pivotally, connected with the brush holding links 30, to which are secured brush clamps 30, mounting the brushes 31. The lower brushes of Fig. 6 are indirectly connected with collar 29 and are intended to engage the neck of the can. Brushes 31 are referred to more in detail below.

For raising and lowering the can holding,

means I provide a sprocket wheel 32 mounted on a stud secured to the frame 1. A chain 34, adapted to be secured to shaft 8, passes over wheel 82, and is secured to the counterweight 36. l/Vheel 32 is also provided with a counterbalance 37, and a connccting rod 38 is pivoted at one end to wheel 32, as shown in Fig. 3, the other end of the rod being pivoted to the end of lever 39 mounted on the brace frame 2 and controlled by operating element 40.

The driving mechanism includes a horizontal shaft 41 (Figs. 3 and 4), mounted in suitable bearings. On the rear end of shaft 41, beyond main frame 1, is secured a driving pulley 43 (Fig. 4),'to be driven from any suita le source of power.

On the forward end of shaft 41 is a beveled gear wheel 44 (Fig. 3), which drives a gear wheel 45 on the hollow brush shaft 5, for rotating the shaft. Within the shaft 5 is another hollow shaft 150 (Fig. 7 for operating the brushes, and a tube 151 within shaft 150 conveys water to the brushes.

A guard or hood 75 (Fig. 1), of the form illustrated, and open at the top and front, prevents the water from being thrown outwardly, and this guard includes a lower funnel-like portion surrounding shaft 8. Bands 76 secure the guard to the frame 1. Flared portions 77 are provided atthe sides of the front opening of the guard, and there is also provided a tray or the like 78 having an inner wall 80, and an outer wall 79, the tray holding a small quantity of water which the operator may use with brush 81, for further cleaning the outside of the can as it is revolved.

The brushes 31 and the hollow shaft construction, shown in Figs. 6 and 7, have already been referred to. The brushes expand or collapse with reference to the shaft when the collar 28, connected with the brushes by means of links 30, moves upon the shaft. Collar 28 is secured to tube 150, by screws 152 extending through slots 5 in shaft 5, so that'the brushes may be collapsed by pulling down tube 150, through the medium of yoke 150 (Fig. 7). The yoke is controlled by lever 149 and bracket 148. As the brushes are revolved within the can, in view of the rotary movement imparted to the brush shaft, they expand or move into contact with the inner surface of the can by centrifugal force.

At the beginning of the operation, lever 92 is pressed downwardly, for the purpose of opening the can holding device, the can being placed in the holder in an inverted position. The pressure on lever 92 is re moved, and the springs 14 effect the closingof the holder. The can and holder are then lowered together by raising lever 40 (Fig. 2), thereby producing partial rotation of wheel 32 (with which the leve 15 indirectly connected). This results in the elevation of weight 36 connected by chain 34 with shaft 8, carrying the can holder. The shaft and can holder then descend.

hen lever 147 of Figs. 2 and 3 is de pressed, rods 146 and 144 of Fig. 4 are elevated, and move arm 139 controlling the valves for admitting fluid to the brush shaft (or the tube within the shaft), and thence to the brushes 31, for cleaning the inside of the can.

The can holder is then released, and the can revolves with the brushes 31, the outside of the can being cleaned by contact with brushes 153 within the holding device.

Various other features of construction, not claimed in this case, are not described herein.

lVhat I claim is- 1. In a device of the class described, a can holding device comprising a plurality of can inclosing and gripping members, mounting means therefor including a plurality of arms, means including a tubular member for supporting the mounting means, a shaft within said tubular member, means for partly rotating the shaft, and means imparting movement from said shaft to the arms.
